I pulled this set out again after doing the initial program when I first received it. I just wanted to use some stand alone weight workouts without a strict rotation and this fit the bill. I'm doing a mix of a 2-3 STS 2.0 workouts with some other Cathe cardio, Katami 4x4 workouts, or other random workouts (not weight oriented) for a total of 4-5 workous per week.
It looks something like this:
Week #1 - Did 2 of the total body workouts with Cathe Hiit and a step workout
Week #2 - Did Upper #1 and Lower #1 with Katami 4x4 and Kettlebell KB.
Week #3 - Did Upper #2 and Lower #2 with Cathe kickbox and Cardio coach.
Week #4 - Did 3 of the single body part mish mosh premixes so-as to do 2 body parts per workout in a single day with added ABs on some days.
This set is so versatile. I just LOVE It. The heavy weights and slow pacing is perfect. Even without a specific rotation I'm seeing some nice hypertrophy gains and have leaned out a bit in my mid section. These workouts also seem really fresh to me so I never really know what I'm in for when I pull out a workout and push play. I didn't experiment with the premixes during the initial rotation so it's really fun to start playing with those.
